Westermo Ethernet Simplifies Onboard Comms Applications

Latest News

Specifically designed for onboard applications, the Viper-212, Viper-112 and Viper 012 twelve-port switches deliver a complete solution for control systems, including improved levels of reliability and simplified network design, installation and maintenance.

The Viper series exceeds the EN 50155 onboard railway standard for electronic equipment, and are designed to achieve the highest mean time between failures of up to 900,000 hours, ensuring the long-term field operation.

The Viper 212 is a managed layer 3 routing switch, The Viper 112 offers managed layer 2 switching functionality and the Viper 012 is an unmanaged solution. These different levels of software functionality allow users to select the most appropriate level of functionality for their network.

The series incorporates M12 connectors that are integrated into the housing to reduce size and further protect against vibration. Sealed to IP65 and vibration resistant to military standards, these units are suited for situations where mechanical stress, dirt or continuous vibrations are present. A Gore-Tex membrane is used to prevent condensation build up by normal climatic day/night cycling.

In the event of any link or hardware failure Westermo’s FRNT technology is able to re-configure a large network in 20ms. The Ethernet switches can be safely accessed from anywhere in the network, or directly via a console port on the Viper switch or an Ethernet or USB port on the RedFox switch.
